REPEATING AIR-RIFLE.

SPECIFICATION forming part of Letters Patent No. 662,054, dated November20, 1900.

Application filed January 4, 1900. Serial No. 299. (ModeL) To all whomit nzay concern:

Be it known that 1', WILLIAM J. BURROW, a citizen of the United States,residing at Plymouth, in the county of Wayne, State of Michigan, haveinvented certain new and useful Improvements in Repeating Air Rifles;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

This invention relates to a repeating spring air-gun; and it consists inthe construction and arrangement of parts hereinafter fully set forth,and pointed out particularly in the claims. J

The object of the invention is to provide for an air-gun of the classdescribed a magazine feed or repeater mechanism in which the arrangementis such as to conveniently retain the slot in a magazine formed betweenthe false barrel and the true barrel of the gun to enable the shot orprojectiles to be fed one at a time into the true barrel of the gun in asimple and efficient manner and to enable the operator to see that ashot or projectile has been fed into the true barrel upon each operationof the feeding device.

The above object is attained by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a general view of a gunembodying my invention. Fig. 2 is an enlarged elevation of the muzzleend of the barrel, showing the screw, by means of which the feeding-diskis actuated, projecting through a slot in the false barrel of the gun.Fig. 3 is a longitudinal section through the true barrel and the falsebarrel as well as the feeding mechanism located between said barrels.Fig. 4 is a longitudinal sectional view through the forward end of thefalse barrel, showing the true barrel therein and the shot-feedingtion,as on line 6 G of Fig. 4. Fig. 7 isa like section, as on line 7 7 ofFig. 4. Fig. Sis an elevation of the muzzle of the gun. Fig. 9 is adetail in longitudinal section through the barrel of the gun and feedingmechanism, as on line 9 9 of Fig. 5.

Referring to the characters of reference, 1 designates the stockof thegun, to which the false barrel? is hinged in the ordinary manner of abreakdown-gun, said false barrel containing an air-chamber, in which aspringpropelled piston (not shown) is adapted to reciprocate in a mannerwell understood in the art. Communicating with the air-chamber 3 (seeFig. 5) is the true barrel 4, having a contracted seat 5 at its breechto arrest and hold the shot or projectile in position for firing whenplaced in said barrel. The false barrel is of greater diameter than thetrue barrel,

which is supported centrally withinthe false barrel. The end of thefalse barrel is closed by a circular plate 6 in the muzzle thereof,through the center of which the true barrel 4 extends.

Mounted upon and made fast to the exterior of the true barrel is aspiral column 7 of such diameter as to fill the interior of the falsebarrel. The spiral formation of said collar serves to direct the shot tothe base thereof. At the base of the incline plane 8 of said spiralcollar is an opening 9, formed through said collar of such diameter asto freely receive the shot. By locating the collar 7 within the falsebarrel, so as to surround the true barrel, a magazine 10 is formed,surrounding the true barrel between the collar 7 and the muzzle-plate 6,adapted to contain the shot or projectiles 'to be fired from the gun,the shot being placed in the magazinechamber through the aperture 11,formed in the plate 6 and communicating with the magazine 10. The shotmay be confined within the magazine by a suitable plate (not shown) toclose the aperture 11.

Secured upon the exterior of the true barrel below the spiral collar7and spaced therefrom is a fixed collar 12, having thereon the radiallugs 13. Mounted upon the exterior of the false barrel, between thecollars 7 and 12, is a rotary disk 14, through the center of which saidbarrel passes and forms the axis of oscillation of said disk. In theupper face of the rotary disk 14 is a ehannel15, extending diametricallyof said disk and adapted to normally register with the aperture 9 in thecollar 7. Formed through the wall of the true barrel 4 is an aperture16, through which a shot is adapted to pass from the channel 15 in thedisk 14L when said disk is rotated, so as to bring the inner end of saidchannel into alinement with said opening 16 into the true barrel, asshown by dotted lines in Fig. 6. The shot upon entering the true barrelfrom the channel in said rotary disk drops to the seat 5 at the breechof said barrel in position for firing, as will be well understood. Therotary disk 14 is actuated by means of a screw or pin 17, which entersthe edge of said disk and projects through a slot 18 in the wall of thefalse barrel, which allows of the travel of said screw as the disk isoscillated. The slot 18 is extended such distance around the barrel asto expose a portion of the channel 15 in the disk 14, as clearly shownin Fig. 2, whereby the operator can determine beyond a question whetheror not a shot by the operation of said disk is discharged from themagazine into the true barrel of the gun.

To maintain the rotary disk 14 normallyin position to cause the channel15 therein to register with the aperture :4 in the spiral collar 7, aspring 19is secured at one end to the barrel of the gun and at the otherend is caused to engage the rotarydisk 14, as clearly shown in Fig. 9,whereby said disk is normally held with its channel 15 directly in linewith the aperture 9 in the collar 7, so that a shot when the parts arein their normal position will pass from the magazine through saidaperture in said collar and lie in said channel in position to bedischarged into the true barrel of the gun by a rotation of said disksufficient to cause said channel to register with the opening 16 in saidbarrel and allow the shot to roll from the channel into the barrelthrough said opening 16 and fall to the seat 5' at the breech of saidbarrel. Upon releasing the actuating-screw 17 of the disk 14: thetension of the spring 19 will return said disk to its normal position,when another shot will drop into the channel thereof through theaperture 9 into the collar 7, whereby it will be seen that through theoperation of said disk the shot may be fed one at a time from themagazine into the barrel of the gun, the parts after each operationrestoring themselves for a succeeding operation. To limit the movementof the disk 14, a ing 20 is formed on the rear face thereof, which liesbetween the lugs 13 on the collar 12 and which is adapted to engage saidlugs to arrest said disk in its movementin both directions. By

providing the collar 7 with a spirally-inclined face 8 the shot arethereby directed to the aperture 9 in the collar at the base of saidincline, so that the last shot in the magazine may be properlydischarged therefrom.

Having thus fully set forth my invention,

what- I claim as new, and desire to secure by Letters Patent, is-

1. In a repeating air-rifle, the combination of the true barrel, amagazine, a channel leading from the magazine into said true barrel, amovable disk having a portion of the channel formed therein, saidchannel in said disk being normally closed from communication with thetrue barrel.

2. In a repeating air-rifle, the combination of the true barrel, a falsebarrel forming a magazine-chamber, amovable disk having a channeltherein, an opening in the bottom of the magazine normally communicatingwith the channel in said disk, the true barrel having an openingtherethrough normally closed by said disk, the channel in said diskbeing adapted to register with the aperture in said barrel by a movementof said disk.

3 In a repeating air-rifle, the combination of the true barrel, ashot--magazine adjacent thereto, the bottom of said magazine having anopening for the passage of the shot therefrom, the true barrel having anopening in the Wall thereof for the passage of the shot into said barrelsaid barrel-opening being out of alinement with the opening in thebottom of the magazine, a movable member having a shot-conveying channeltherein adapted to be moved to cause said channel to alternatelyregister with the opening in the bottom of the magazine and the openingin the wall of the true barrel.

4. In a repeating air-rifle, the combination of the false barrel, thetrue barrel therein and spaced therefrom, a magazine-chamber within thefalse barrel surrounding the true barrel, said magazine-chamber havingan inclined bottom, provided with an aperture at the base of saidincline, the true barrel having an aperture through the wall thereof, amovable part mounted on the true barrel and adapted to close theaperture therethrough, said movable part having a shot-receiving channelin its upper face which normally registers with the aperture in thebottom of the magazine, said channel in said part being adapted toregister with the aperture in the barrel by a movement of said part anda spring engaging said movable part.

5. In a repeatingair-rifle, the combination of the false and the truebarrels, the magazine within the false barre], a shot-conveying channelleading from the magazine into the true barrel, a movable part having aportion of said channel formed therein, a slot in the wall of the falsebarrel through which a portion of the channel in said movable part isvisible and means for moving said movable part.

In testimony whereof I sign this specification in the presence of twowitnesses.
